摘要： In a process which is before a treatment process of forming a chemical conversion, TiO2 fine particles as an electron releasing-related substance (electron releasing substance) are attached onto a surface of a vehicle body. Then, a chemical conversion treatment is applied to the vehicle body having the TiO2 fine particles attached thereto. Thereby, an energy band gap of a finally-formed chemical conversion film can be smaller than that of a chemical conversion film formed by using only a chemical conversion treatment agent. Accordingly, the number of electrons (free electrons) which can be supplied onto the surface of a chemical conversion film can be increased during a voltage application in an electrodeposition coating process, and reducing reaction at a cathode can be promoted.
摘要翻译：在化学转化处理过程之前的过程中，作为电子释放相关物质（电子释放物质）的TiO 2微粒附着在车体的表面。然后，对附着有TiO 2微粒的车身施加化学转化处理。因此，最终形成的化学转化膜的能带隙可以小于仅使用化学转化处理剂形成的化学转化膜的能带隙。因此，在电沉积涂覆工艺中的电压施加期间，可以提高可供给到化学转化膜的表面上的电子数（自由电子数），从而可以促进阴极的还原反应。
